Lake-Effect Snow Warnings for Three States as Alert Issued to Drivers [Video]

Heavy snowfall is expected in the Great Lakes region this week, with lake-effect snow warnings across New York, Ohio and Pennsylvania.

The National Weather Service warnings, which are in place until varying times, highlight driving conditions as particularly hazardous.

In late fall and winter, lake-effect snow is a common occurrence in the Great Lakes region.

“Lake-effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more,” the NWS said on its website.

In all states, drivers are warned to consider delaying travel plans. If you must travel, the NWS advises carrying food, water and an extra flashlight in your car in case of an emergency.
